In order to protect the school grounds from the ever present threat of the bugs, today it's Arsnotoria's turn to be on extermination duty.
Mell, Little Alberta, Picatrix, and Abramelin all rush to her side to help her with this activity.
But then, one word from their shadow cat teacher Perdura puts the entire school into a frenzy!?
Perdura, you shouldn't talk 
behind someone's back.
.بيردورا، لا ينبغي أن تغتابي أحدهم
Perdura, man redet nicht über
andere hinter ihrem Rücken.
Perdura, no critiques
a la gente a sus espaldas.
Perdura, no critiques
a la gente a sus espaldas.
Voyons, Perdura.
Ne casse pas du sucre sur son dos.
Non si parla male degli assenti, Perdura!
Perdura, não fale dos outros pelas costas.
Пердюра, нельзя судачить о людях
у них за спиной.
